How do i view all photos on ipad that haven't been added to an album yet?

Question

I have over a thousand pictures on my iPad. I want to sort them into albums. But I am running into difficulties.
(1) After adding a bunch of images to various albums, I am sure I missed a few. Is there a way to just see ONLY those pictures that have NOT yet been added to any album? Can this be done in Photos app, or do I have to buy iPhoto or something else?
(2) Is there any app that can overlay on top of each image thumbnail a set of icons where each overlaid icon represents one of the albums that the photo is currently in?
Thanks.

No... the whole point of my question is that I want to organize my photos on my iPad prior to putting them on my computer. I have a lot of "dead time" on the bus/train/plane where using iPad for this would be ideal. I find it shocking that it lacks this basic capability in the built-in software.
Surely there must be an app which can access the images I've already imported to iPad using the Camera Connection Kit, and allow me to sort them out into folders or albums. Photos app already does most of what I'd like it to do, but it does not let you filter images by which albums they don't belong to. I.e. you can't see which images aren't sorted into at least one album yet. Photos app also lacks metadata viewing/filtering/tagging/rating. Heck even my PS3 can show metadata...!
I am constantly mystified at Apple's lack of what I would consider pretty basic features. There are some ideas, like the classic Mac GUI file/folder desktop analogy, that to me are timeless. I have yet to see the benefit or advantage to iOS's crippling lack of the ability to work with files in a logical or direct way. I do understand how letting the app itself organize its own documents into directories itself helps it keep track of files for the purposes of using CoreData to create more informative views and organizational structures. However in Unix there are abundant ways to have this cake and eat it too -- you can do what TimeMachine does, which is to create hard links to files, so any given file can simultaneously exist in multiple different folders without necessitating duplicated data. Why can't Photos app therefore let me organize my files into folders the way I want to, in a standard, Mac-like way, without disrupting its own DB, simply by usig hard links or symbolic links, or something like this? Why not have file system layer that refers to each file by a UUID instead of by a directory path?
I am so tired of the gimped file system of iOS. First they said it was for security on iPhone. But then when iPad came out and it was the same way, then the excuse changes to, "People just like it better this way, and so should you." Wait, so 1984-2007 didn't happen...? You can't suddenly act like the Macintosh desktop analogy is suddenly an irrelevant bad idea. Just because people suffer through the lameness that is iTunes File Sharing, doesn't mean they universally would like it better if they could just access their files right in the Finder instead of through a kludge-funnel.
